We've all been driving and come upon signs warning us that construction is happening and we have to slow down for the safety of workers and that penalties are going to be doubled. We see billboards with children imploring us to reduce speed because their parents are highway construction employees.

Then it turns out that there is no construction. Speed limit credibility is put to the test by those instances and as a result, people have been routinely ignoring speed limits, according to Dr. Ross Blackman, a scholar at Queensland University of Technology Centre for Accident Research&Road Safety - Queensland, who presented the findings at the Occupational Safety in Transport Conference on the Gold Coast in Australia.

As has been predicted for some time, there is a physics train wreck coming at the semiconductor industry - a size and speed where atoms have reached their limits. Quantum computing has remained a dream for 20 years with little progress, which means chips will have to start getting bigger again, to get better performance - or we settle for playing Angry Birds.

The present size and speed limitations of computer processors and memory could be overcome by replacing silicon with phase-change materials, which are capable of reversibly switching between two structural phases with different electrical states – one crystalline and conducting and the other glassy and insulating – in billionths of a second. 

Circular RNA were discovered a few years ago, but their role in our bodies is poorly understood. 

Our genetic information is stored in DNA, tiny strands of nucleic acid that contain instructions for the functioning of our bodies. To express this genetic data, our DNA is copied into RNA molecules, which then translate the instructions into proteins that perform tasks in our cells. Several years ago, scientists discovered a new type of RNA molecule. Unlike all other known RNAs, this molecule is circular, and was labeled circular RNA.

Referrals for genetic testing more than doubled across the UK after actress Angelina Jolie announced in May that she proactively underwent a double mastectomy due to testing positive for a BRCA1 gene mutation.

The rise in referrals continued through to October, long after the announcement was made, according to findings in Breast Cancer Research.

The wage gap between government employees and the private sector is already large and growing. Now there will be a gap in benefits due to the Patient Protection and Affordable Care Act (AKA Obamacare) also.

Employees working for Fortune 500 companies can expect to pay higher employee contributions for their health insurance, according to a survey of chief human resource officer.

Patrick Wright, a professor in strategic human resource management at the University of South Carolina, directs the annual the HR@Moore Survey of Chief HR Officers. The survey is distributed to more than 560 CHROs of Fortune 500 companies and members of HR Policy Association, a professional organization. 

A new study uses tree rings to document arroyo evolution along the lower Rio Puerco and Chaco Wash in northern New Mexico.
